Abstract
An orbital tensioner comprising a base, a carrier engaged with the base and revolvable about an axis A-A, a first pulley journalled to the carrier, a pivot arm mounted to the carrier, the pivot arm pivotable about an axis B-B, a second pulley journalled to the pivot arm, the axis B-B is orbitally movable about axis A-A, a spring engaged between the carrier and the pivot arm, and a damping mechanism frictionally engaged between the carrier and the base to damp a carrier movement.
Claims22
A tensioner comprising:
- a base (101);
- a carrier (103) engaged with the base and revolvable about an axis A-A;
- a first pulley (104) journalled to the carrier;
- a pivot arm (105) mounted to the carrier, the pivot arm pivotable about an axis B-B;
- a second pulley (106) journalled to the pivot arm;
- the axis B-B is orbitally movable about axis A-A;
- a spring (110) engaged between the carrier and the pivot arm;
- and
- a damping mechanism (111) frictionally engaged between the carrier and the base to damp a carrier movement.
A tensioner comprising:
- a base;
- a carrier engaged with the base and revolvable about a first axis A-A;
- a first pulley journalled to the carrier;
- a pivot arm pivotally mounted to the carrier about a second axis B-B;
- a second pulley journalled to the pivot arm;
- the second axis B-B orbitally about the first axis A-A, the second axis B-B parallel to the first axis A-A;
- a spring engaged between the pivot arm and the carrier urging the first pulley toward the second pulley;
- and
- a damping mechanism frictionally engaged between the carrier and the base to damp a first member movement.
